HOLDING MOUNT
The present invention relates to a holding mount, in particular of or for a
commercial
vehicle trailer, to a holding system and to a mounting plate.
Holding mounts of the type addressed here are used, in particular, to mount
chassis
components. To this end, the holding mounts are fastened to a load-bearing
struc-
ture, for example a commercial vehicle frame, said holding mounts having
openings
or bearing points, in order, for example, to rotatably mount a longitudinal
link and/or to
arrange a spring or shock absorber element, etc. The known holding mounts
entail
the disadvantage that they are either very heavy, which reduces the available
payload
of the vehicles, or secondly do not have the required rigidity/strength.
It is therefore an object of the present invention to specify a holding mount,
a holding
system and a mounting plate which eliminate the abovementioned disadvantages
and, with a low build-up of material, make a very rigid fastening or
attachment of
chassis components to a load-bearing structure possible.
According to the invention, a holding mount, in particular of or for a
commercial vehi-
cle trailer, comprises two side walls which extend along a vertical axis and
which form
an arrangement region, for arranging the holding mount on a load-bearing
element,
the holding mount comprising an insert part which has a connecting section and
a
reinforcing section, the connecting section also forming the arrangement
region, and
the reinforcing section extending between the side walls for the reinforcement
pur-
poses. Here, the reinforcing section can extend substantially along or
parallel to the
vertical axis or can be inclined with respect to the latter, an
1

-
CA 03023977 2018-11-13
angle of inclination of up to 300, preferably of up to 150 and particularly
preferably
of up to 50 being preferredAn accordance with different embodiments, the load-
bearing element can be a frame structure or a part of a frame structure of a
vehi-
cle, in particular of a commercial vehicle trailer. As an alternative,
however, the
load-bearing element can also be a mounting plate which for its part is
arranged
again on a frame structure of a vehicle. In one preferred embodiment, the load-
bearing element is a mounting plate, in particular made from steel, which is
fas-
tened, in particular screwed, to a frame structure or to a part of the frame
struc-
ture, for example a frame of a commercial vehicle trailer. The frame of the
trailer,
comprising at least one longitudinal carrier, is preferably manufactured from
alu-
minum. In the installed state of the holding mount, the abovementioned
vertical
axis lies substantially perpendicularly with respect to a roadway plane or to
a sur-
face extent of the load-bearing element. In one preferred embodiment, the two
side walls are connected via a transverse wall. The holding mount is
preferably
manufactured by way of a forming method, in particular by way of bending of an
initially plate-shaped component. The arrangement region provides the actual
connecting point between the holding mount and the load-bearing element, a
part
of the arrangement region particularly advantageously also being formed by way
of the insert part, that is to say also forming or configuring it. At the same
time, the
insert part advantageously fulfills a reinforcing function, by extending
between the
side walls along or in an inclined manner with respect to the vertical axis,
said in-
sert part bearing against the side wails and supporting the latter, in
particular even
with respect to one another, as a result of which buckling, folding or
collapsing of
the holding mount in the case of loading is prevented. Here, "along the
vertical
axis" does not mean or specify a specific direction. The reinforcing section
can
extend substantially parallel to or else obliquely or in an inclined manner
with re-
spect to the vertical axis, very generally substantially in the direction of a
lower end
of the holding mount. The reinforcing section therefore advantageously
connects
the side walls, whereas the connecting section forms an arrangement region
with
a contour which is preferably circumferentially closed. Said closed contour
makes
(in particular, circumferential) welding of the holding mount to the load-
bearing el-
ement possible. Offsetting therefore does not have to be carried out during
weld-
ing and no edges or steps have to be welded. The welding operation can, as it
were, be performed in one step or "seamlessly". The insert part is also
advanta-
2

geously at the same time fixed relative to the holding mount during the
welding of
the holding mount to the 'odd-tear-int:1 elemeht-ty Way of the configuration
of the
holding mount, comprising the insert part which has the connecting section and
also forms the arrangement region. In one work step, the two components can
therefore be fastened The reinforcing section which extends within the side
walls
can likewise be welded, but it can also merely bear on the inside against the
side
walls in a positively locking manner. The insert part is preferably configured
from
steel, like the holding mount per se. It is particularly advantageous to
configure the
insert part as an element which is separate from the side walls. In other
words, the
insert part and the side walls are manufactured separately, it then being
possible
for them to be connected to one another, in particular to be connected in an
inte-
grally joined and/or non-positive positively locking manner.
The connecting section of the insert part expediently has an inner section
which
extends between the side walls in the arrangement region. The connecting
section
therefore connects the side vvalls directly to one another and to this end
bears
against the inner faces of the side wails. it therefore reinforces, in
particular, the
arrangement region of the holding mount.
In accordance with one erribodimen, the connecting section has an outer
section
which bears against the side walls in the arrangement region", in particular
so as to
close an outer contour of the side walls The outer section therefore does not
bear
against the inner faces of the side wz.111s, but rather against the edges or
edge fac-
es of the side wall's. Ashes been mentioned, an.cuter contour of the side
walls
can be continued, in particular in the arrangement region, by way of said
refine-
ment. By way of the oUter section, the arrangenient region or a length of the
ar-
rangement region can be enlarged, which contributes to an additional reinforce-
ment of the overall arrangement. Moreover, the continuation of the contour
rein-
forces the welded conneetion; since, for example, the outer section preferably
has
a substantially SemicircUlar structure, in orderio close or to connect the
side walls

uniformly.
The outer section and the inner section of the insert' part are expediently
connect-
ed above the shoulder, a size of the shoulder corresponding substantially to a
wall
. . .
,
,

thickness of the side wall or walls. The connecting section is therefore
expediently
connected to the side walls in a positively locking manner, as a result of
which
locking and pre-positioning of the insert part relative to the holding mount
are
made possible. The addressed locking and pre-positioning are also achieved, in
particular, by virtue of the fact that the insert part has a wall thickness
which is
greater than a wall thickness of the side walls, a ratio of a wall thickness
of the
side walls to a wall thickness of the insert part Eying in a range of
approximately
from 0.4 to 0.8, preferably in a range of approximately from 0.5 to 0.7. The
rela-
tively great wall thickness of the insert part expediently of course also
contributes
to a greater strength and/or rigidity of the overall holding mount.
In accordance with one preferred embodiment, the reinforcing section extends
substantially parallel to the vertical axis, the connecting section extending
substan-
tially perpendicularly with respect thereto. The reinforcing section and the
connect-
ing section preferably therefore have substantially a 90 angle with respect
to one
another. As an alternative, however, the angle can also be greater or smaller
than
90 , for example in a range of approximately from 80 to 130 , preferably from
85
to 100 .
A length of the holding mount is measured along the driving direction in the
in-
stalled state. As a rule, a length of the arrangement region corresponds
approxi-
mately to a length of the holding mount. In preferred embodiments, a ratio of
a
length of the connecting section to-a length of the arrangement region lies in
a
range of approximately from 0.1 to 0.5, expediently in a range of
approximately
from 0.2 to 0.3.A ratio of a length of the reinforcing section (parallel to
the vertical
axis) to a length of the Connecting section (perpendicularly with respect to
the ver-
tical axis) lies in preferred embodiments at approximately from 1.1 to 1.3.
In accordance with one preferred embodiment, the holding mount widens along
the vertical axis away from the arrangement region, the reinforcing section
prefer-
ably extending into the widened region. A ratio of the width of the tapered
region to
the width of the widened region expediently lies at approximately from 0.5 to
0.95,
preferably from 0.7 to 0.9. The tapering in the direction of the arrangement
region
entails the advantage that material can be saved as a result. Moreover, a very
rig-
4
CA 03023977 2018-11-13
id structure is provided and it is made possible to fasten a holding mount of
this
type even to very narrow (longitudinal) carriers. The fact that the
reinforcing sec-
tion extends as far as into the widened region entails the advantage that
firstly the
widened region is also reinforced and secondly precisely said transition zone
is
also reinforced. It has thus been shown that compressions or buckling of compo-
nents can occur precisely in the region of (cross-sectional) transitions of
this type.
It is therefore particularly advantageous that the insert part contributes to
a rein-
forcement of the holding mount even in said region.
In accordance with one preferred embodiment, a ratio of a width of the tapered
region to the widened region lies at approximately from 0.7 to 0.9. Said
values rep-
resent an ideal compromise between as low a material use as possible, with at
the
same time as high a. rigidity as possible.
A fastening opening for a chassis component is expediently arranged below the
inner section of the insert part. The region below the inner section is
extremely
rigid and provides a very rigid attaching possibility for chassis components,
such
as a spring element. Further fastening openings for arranging chassis compo-
nents, such as a longitudinal carrier, are advantageously provided in the
holding
mount. For example, a bearing point, in the form of a corresponding opening or
bore, is preferably arranged, in particular, in the widened region, which
bearing
point serves to mount a longitudinal link. On account of its dimensions, the
wid-
ened region also provides the necessary bearing width.
The insert part expediently has at least one recess or opening, as a result of
which
it is brought about advantageously that further weight can be saved. Recesses
or
openings of this type can be, for example, oval, round, in particular
circular, or else
polygonal. Recesses of this type are expediently provided in the connecting
sec-
tion and/or in the reinforcing section.
The invention is also directed to a holding system, comprising a holding mount
which comprises two side walls which extend substantially along or in an
inclined
manner with respect to a vertical axis, and which form or configure an arrange-
ment region which is arranged on a load-bearing element, the holding mount com-
5
CA 03023977 2018-11-13
prising an insert part which has a connecting section and a reinforcing
section, the
connecting section also forming or configuring the arrangement region, and the
reinforcing section extending between the side walls along the vertical axis
for the
reinforcement purposes.
Further advantages and features of the holding mount according to the
invention
and its preferred embodiments can likewise be used in the holding system
accord-
ing to the invention.
In accordance with different embodiments, the load-bearing element is a frame
structure or a part of a frame structure of a vehicle, in particular a
commercial ve-
hicle trailer, or a mounting plate. In accordance with one preferred
embodiment,
the load-bearing element is a mounting plate, in particular made from a steel
mate-
rial. The holding mount is likewise preferably made from a steel material. The
mounting plate advantageously comprises corresponding fastening openings for
the positively locking and/or non-positive connection, in particular, for
example, for
screwing, to the frame, for example of the commercial vehicle trailer. In one
pre-
ferred embodiment, the said frame is manufactured from aluminum, whereas the
mounting plate and the holding mount are manufactured from steel. The mounting
plate and the holding mount are expediently connected via the arrangement
region
in an integrally joined manner, in particular via a welding method. The
mounting
plate is in turn advantageously screwed to the frame.
In one preferred embodiment, the load-bearing element, in particular therefore
the
mounting plate, has a mounting opening, within which or on which the holding
mount or its arrangement region is welded.
The mounting opening particularly preferably has a web or collar, the holding
mount or the arrangement region being arranged or fastened within the web or
the
collar. The mounting opening entails the advantage that the weight of the
mount-
ing plate can be reduced as a result. In addition to an optimum welding
surface,
the web or collar in turn entails the advantage that the mounting plate per se
and,
moreover, the arrangement of the holding mount relative to the mounting plate
are
reinforced.
6
CA 03023977 2018-11-13
A circumferential, closed gap is particularly preferably formed between the
web or
collar and the arrangement region. Said gap is highly suitable as a welding
zone,
since, as has been mentioned, it is circumferential and, as a result of its
geometry,
provides a sufficiently great area for connecting the different joint
partners. The
holding mount is particularly preferably welded onto the mounting plate from
above. As an alternative or in addition, the holding mount can also be welded
onto
the mounting plate from below.
Finally, the invention also relates to a mounting plate, comprising a mounting
opening, for arranging a holding mount, in particular a holding mount
according to
the invention, the mounting opening being reinforced, in particular by way of
a web
or collar. If the reinforcement is configured as a web or collar, this also
entails the
advantage that space or a place for the welded seam is provided. The web or
col-
lar is expediently configured in such a way that it extends in the direction
of the
holding mount which is to be arranged or is arranged. In preferred
embodiments,
the web or collar assumes, for example, a height of approximately from 3 to 10
mm.
Further advantages and features result from the following description of one
pre-
ferred embodiment of the holding mount, the holding system and the mounting
plate with reference to the appended figures, in which:
figure 1: shows a perspective illustration of one embodiment of a holding
mount,

hold-
ing mount which is known from figure 1,

Fig. 1 shows a perspective illustration (obliquely from above) of a holding
system,
comprising a holding mount 10 which comprises two side walls 11, and a load-
bearing element 60. The side walls 11 comprise a very wide variety of
fastening
openings 28 which serve, for example, to mount a longitudinal link (not shown
here). The holding mount 10 is connected via an arrangement region 20 to the
load-bearing element 60 which is a mounting plate 60 in the embodiment which
is
shown here. An insert part 40 can be seen in the region of the arrangement
region
20, which insert part 40 also forms the arrangement region 20. In particular,
a
connecting section 41, an inner section 42 and an outer section 43 can be
seen. It
becomes clear, in particular, that an outer contour 12 of the side walls 11 is
con-
tinued by way of the outer section 43 of the insert part 40, with the result
that a
circumferential gap 66 is formed in interaction with a web/collar 64 of the
mounting
plate 60, which circumferential gap 66 is ideally suitable for welding the
holding
mount 10 to the mounting plate 60, since firstly a great welding area is
provided
and secondly a welded seam of this type is ideally embedded into the entire
con-
struction/structure. It is also to be mentioned with regard to the insert part
40 that
its inner section 42 and its outer section 43 are advantageously connected via
a
shoulder 45 which corresponds approximately to a wall thickness of the side
walls
11. Ideal positioning of the insert part 40 within the side walls 11 is made
possible
by way of said structure. The mounting plate 60 is also provided with
fastening
openings (not designated in further detail) which expediently serve to arrange
the
holding system, comprising the mounting plate 60 and the holding mount 10, on
a
frame (not shown here), for example a longitudinal carrier of a commercial
vehicle
trailer.
Fig. 2 shows the holding system which is known from figure 1 from another per-
spective, namely substantially obliquely from below, a vertical axis being
denoted
by the designation H. It can be seen in said perspective that the two side
walls 11
are connected via a transverse wall 11'. It can be seen clearly, moreover,
that the
holding mount 10 comprises a tapered region 22 and a widened region 24. In
addi-
tion to the already known connecting section 41, the insert part 40 comprises
a
reinforcing section 44 which extends substantially perpendicularly with
respect to
said connecting section 41 and advantageously extends as far as into the
widened
region 24 in the embodiment which is shown here. In particular, the transition
re-
8
,
CA 03023977 2018-11-13
gion between the tapered region 22 and the widened region 24 is also
reinforced
by way of the reinforcing section 44. In said perspective, the web or collar
64 can
also be seen more clearly, which web or collar 64 advantageously forms the gap
66 which is shown in figure 1. It has been mentioned in conjunction with
figure 1
that the welding expediently takes place from above. As an alternative or in
addi-
tion, the welding of the holding mount 10 can also take place from below, for
ex-
ample on the underside of the web/collar 64. It can also be seen in said
perspec-
tive that the holding mount 10 is supported laterally via a strut 80, said
support
taking place here relative to the mounting plate 60. The strut might also,
however,
be attached to the frame or to another part of the vehicle. Below the
connecting
section 41, the tapered region 22 has a fastening opening 28 which is
additionally
provided with a fastening collar 30 in the embodiment which is shown here. For
further weight saving, the insert part 40 has two recesses or openings 46.
.. Fig. 3 shows that embodiment of a holding system which is known from
figures 1
and 2 in a side view. Here, in particular, the substantially right-angled
structure of
the insert part 40 can be seen, comprising the connecting section 41 and the
rein-
forcing section 44. The course of the strut 80 which comprises two carriers in
the
embodiment which is shown here is indicated using dashed lines. Furthermore,
the refinement of the collar or web 64 which extends in the direction of the
holding
mount 10 can be seen. The designation F denotes a driving direction. In the in-
stalled state of the holding mount 10, for example, a longitudinal carrier
would ex-
tend to the right.
Fig. 4 shows a plan view of one preferred embodiment of a mounting plate 60,
comprising a mounting opening 62 which is provided with a web or collar 64.
Said
web or collar 64 can be manufactured, for example, by way of a forming manufac-
turing method. On its edges, the mounting plate 60 has various openings or
bores
which serve to fasten the mounting plate 60, for example to a vehicle frame or
a
longitudinal carrier. The mounting plate 60 is preferably manufactured from
steel;
the provision of the mounting opening 62 is to be mentioned as being advanta-
geous, in particular, since it decisively contributes to the weight reduction
of the
mounting plate 60. At the same time, the rigidity of the mounting plate 60 is
in-
creased significantly by way of the provision of the web or collar 64.
